<P><STRONG>Function</STRONG>
<P>
Creates an
Array
containing evenly spaced data.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
RegularArray DXNewRegularArray(Type t, int dim, int n,<BR>
                               Pointer origin, Pointer delta)<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>
The new Array Object represents a Regular Array of
<TT><STRONG>n</STRONG></TT>
points starting at
<TT><STRONG>
origin
</STRONG></TT>
with a spacing of
<TT><STRONG>delta</STRONG></TT>.  The rank is assumed to be 1, and the shape is
<TT><STRONG>dim</STRONG></TT>.  Both
<TT><STRONG>
origin
</STRONG></TT>
and
<TT><STRONG>
delta
</STRONG></TT>
are assumed to point to items
of the same type as the items in
<TT><STRONG>a</STRONG></TT>.
<P>
Type <TT><STRONG>t</STRONG></TT> is one of the following:
<PRE><STRONG>
TYPE_BYTE            TYPE_HYPER        TYPE_SHORT
TYPE_UBYTE           TYPE_INT          TYPE_USHORT
TYPE_DOUBLE          TYPE_UINT         TYPE_STRING
TYPE_FLOAT
</STRONG>
</PRE>
<P>
Regular Arrays are most often used as constituents of Product Arrays
for the compact representation of regular grids of positions.
<P>
In previous versions of the Data Explorer software, regular arrays with
zero delta values were used to store constant data.  This type of data
can now be stored in a Constant Array.
<P>
The Array created can be deleted with DXDelete.
See <A HREF="progu023.htm#HDRMEMNG">4.2 , "Memory Management"</A>.
<P><STRONG>Return Value</STRONG>
<P>
Returns the Regular Array or returns <TT><STRONG>NULL</STRONG></TT> and
sets an error code.
